Figure 25. Detailed planar view of the combined National Oceanic and Atmospheric Administration surveys in Block Island Sound showing storm-wave induced scour on the flanks of the bathymetric high along the southeastern edge of the study area. Note the relatively flat, featureless appearance of the surrounding seabed composed of Holocene marine sediments, the boulders on the floor of the depressions, and the presence of outliers of the original sea-floor sediments.
